This section presents only the IBM TotalStorage Productivity Center for Disk, which is the

component used to collect and monitor performance for the IBM TotalStorage DS6000.

4.3.2 IBM TotalStorage Productivity Center for Disk

IBM TotalStorage Productivity Center for Disk allows you to manage the disk systems. It will

discover and classify all disk systems that exist and draw a picture of all discovered disk

systems. This utility provides the ability to monitor, configure, create disks, and do LUN

masking of disks. It also does performance trending and performance threshold I/O analysis

for both real disks and virtual disks. It also does automated status and problem alerts via

SNMP. IBM TotalStorage Productivity Center for Disk was formerly the IBM TotalStorage

Multiple Device Manager.

The disk systems monitoring and configuration needs must be covered by a comprehensive

management tool like the TotalStorage Productivity Center for Disk. The requirements

addressed by the TotalStorage Productivity Center for Disk are shown in Figure 4-22 on

page 111.

In a SAN environment, multiple devices work together to create a storage solution. The

Productivity Center for Disk provides integrated administration, optimization for interacting

SAN devices, including:

򐂰 IBM TotalStorage DS4000 family

򐂰 IBM TotalStorage Enterprise Storage Server

򐂰 IBM TotalStorage DS8000 and DS6000 Series

򐂰 IBM TotalStorage SAN Volume Controller

It provides an integrated view of the underlying system so that administrators can drill down

through the virtualized layers to easily perform complex configuration tasks and more

productively manage the SAN infrastructure. Because the virtualization layers support

advanced replication configurations, the Productivity Center for Disk product offers features

that simplify the configuration and monitoring. In addition, specialized performance data

collection, analysis, and optimization features are provided.

As the SNIA standards mature, the Productivity Center view will be expanded to include

CIM-enabled devices from other vendors, in addition to IBM storage. Figure 4-23 on page 112

represents the Productivity Center for Disk operating environment.

The Productivity Center for Disk layers are open and can be accessed via GUI, CLI, or

standard-based Web Services.The Productivity Center for Disk provides the following

functions:

򐂰 Device Manager

򐂰 Performance Manager

Device Manager

The Device Manager is responsible for the discovery of supported devices; collecting asset,

configuration and availability data from the supported devices; and providing a limited

topography view of the storage usage relationships between those devices.

The Device Manager builds on the IBM Director discovery infrastructure. Discovery of storage

devices adheres to the SNIA SMI-S specification standards. Device Manager uses the

Service Level Protocol (SLP) to discover SMI-S enabled devices. The Device Manager

creates managed objects to represent these discovered devices. The discovered managed

objects are displayed as individual icons in the Group Contents pane of the IBM Director

Console as shown in Figure 4-24 on page 113.
